C# :: Populate Textboxes And ComboBoxes Through Data Grid View?
Dec 23, 2011
i m working on a simple project, i want to populate my text boxes and comboBoxes through DataGridView, means when i double click on cell content then the text boxes are populated.my question is that if i have to populate comboBox with the specific value then what i have to do then because comboBox.selectedItem is an object but my class property is a string..
e.g
combobox shows 30 days in it and my class is Code: class account
{
public string day{set;get}
[Code]....
but that does not happen because "comboBox.selectedItem" is an object so if i have to do that what i have to do then?

I need to take a single column and all the rows in the column from a datagridview to a listbox using a for loop. My code is giving me no errors just not showing any data in the listbox.
private void frmProject6_Load(object sender, EventArgs e) {
// TODO: This line of code loads data into the 'enrollmentsDataSet.Enrollments' table. You can move, or remove it, as needed.
this.enrollmentsTableAdapter.Fill(this.enrollmentsDataSet.Enrollments);

I don't really have an issue with the math behind this, rather it's more with the code structure itself. Basically, every row is right, except for the last row. The last row (year) needs to be depreciated by the value at the beginning of the last row (year).

im trying to populate a datagrid, i have a datbase class
public static List<Product> LoadProduct()
{
....................
}
i have a product class
gettor & settors
public Product(int id, string Name, double Price, int Quantity)
{
productId = id;
productName = Name;
productUnitPrice = Price;
productQuantity = Quantity;
}
ive added the HTML code to set up the datagrid, which i can see via design tab, but filling it up is harder.
i uderstand it needs a
protected System.Data.SqlClient.SqlDataAdapter sqlDataAdapter1;
sqlDataAdapter1.Fill();// where it require a dataset or datatable
DataGridProduct.DataBind();
as it requires a datatable i converted the list to a datatable when i run it it says null, im not sure where im going wrong, i noe the list works as i tried populating on a table.
public static DataTable ToDataTable<T>(List<T> items)
{
}

I'm trying to extract data from a grid, it's a Dev Express grid. I have got an object which if I hover over it in debug mode shows me the data I'm after. In the code below if I hover over "row" I can drill down through "Row" and then "ItemArray" and I can see the data I want in an array but I can't find how to get at it.
private void gridShowUsers_Click(object sender, EventArgs e)
{
Object row = gridView1.GetFocusedRow();
string [] rowarray = new string [50];

I am trying to complete this program and as far as I am aware, the only thing not working correctly is populating the listview with my data. I've been stressing over this for a few days and achieving no success. I have to load data from two text files (incidents.txt and technicians.txt), then use a query to populate a listview with all incidents that have been closed. Also, I have to use LINQ for this assignment, so I cannot change anything that would alter my use of that. I'm thinking that perhaps the problem is with my code in form1.cs?Included are all my classes,txt files, etc.

why filtering don't work??
This is code for load data into dataGridView
private void Izvestaj_Load(object sender, EventArgs e) {
connection.ConnectionString = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:UsersTomyDesktopzadatak2zadatak2fedek_OldVersion(2002-2003).mdb;User Id=admin;Password=;";
dt = new DataTable();
OleDbDataAdapter sda = new OleDbDataAdapter("SELECT korisnici.korisnik,dogadjaji.dogadjaj,Tomislav.Datum
[Code] .....
And this is code for filtering by typing into textbox, when type nothing happening
private void textBox3_TextChanged(object sender, EventArgs e) {
DataView DW2 = new DataView(dt);
DW2.RowFilter = string.Format("dogadjaji.dogadjaj LIKE '%{0}%'", textBox3.Text);
dataGridView1.DataSource = DW2;
[Code] .....
And this is by filtering on dataPickers, range of date, and show me what happens on that dates, but show me exception when click button
private void button1_Click(object sender, EventArgs e) {
if(dateTimePicker1.Value>dateTimePicker2.Value) {
MessageBox.Show("Takav opseg nije moguc. Datum Od mora biti veci od datuma Do.", "Opseg datuma", MessageBoxButtons.OK, MessageBoxIcon.Error);

I'm working on an app which monitors user selected data sets from various devices, and I'd like to display the data in a CListCtrl. This would be very convenient, but I'm just a little concerned about (1) just how fast can a CListCtrl be populated, and (2) how can i reduce or eliminate screen flicker. To be specific...
1. There will likely be upwards of 100 rows of data, maybe more (probably 5 or 6 columns), and I'm going to have to refresh it all as quickly as possible, perhaps as fast as once per second. I can play games and only refresh a visible rectangle, but how responsive the control would be, having all that data deleted and refreshed continually?
2. You can see why I'd be worried about screen flicker, and I thought I'd likely have to make two identical overlapped controls so I could double buffer as I would with a graphic animation, switching the visibility of one or another control after its updated to give the appearance of sudden complete updates. BUT... I see there is an extended style you can set called "LVS_EX_DOUBLEBUFFER"

I've got a Dev Express hierarchical grid and I need to which row is in focus in the level that's in focus. In the code below I need to replace "gridControl1.FocusedView.GetRow(0)" with "gridControl1.FocusedView.GetRow(x)" where x is the row number in the focused row but I can't find a property for it.

I've found that with streamwriter(sw) the data isn't displayed with the written to document until you either leave scope or use sw.close I'd prefer to keep sw open as I will be writing to the file in and out, sometimes very frequently, but would also prefer the data to be viewed in real time. Is there an efficient way of going about this?

I have a program which generates lots of data points in 2D (x and y co-ordinates). Perhaps 1,000,000+ of these points. These are floating point numbers. The values all fall within a specific range -R/2 and +R/2.
I want to impose an 'imaginary' grid. Such that I can collect the number of each of these points falling within a specific grid location. The actual 'grid' size is variable.
Should I try and collate this data from my C++ program and then post-process it in some other s/w like matlab?

I have a program I have been working on where the user selects a date and enters the number of days to be viewed in the Calendar.cshtml view. This input renders another view (Update.cshtml) that contains two date picker boxes, one that should contain the selected date and the second one that should contain the calculated date. I am having an issue getting the date selected in the first view to populate to the first date block on the second view as the default and getting the calculated date to populate the second date block in the Update.cshtml view. In addition given the two dates, I would like to generate a calendar, which is why I chose the date picker approach and setting static dates.
Here is my code:
**CalendarController:**
using System.Web.Mvc;
using VanickCalendarApp.Models;
using System;
namespace VanickCalendarApp.Controllers {
public class CalendarController : Controller {

How you can touch a datagridview and it would insert the name it has for a product into a label or textbox.... As I have looked all over and I can't really find a proper way it is mentioned or maybe I am not applying it correctly.

I am trying to get a datagrid working in my program with populating a simple set of data. Which i can then expand on and bring in data from a database.
But even this little simple test datagrid does not seems to be working.
XAML Code
<DataGrid Grid.Row="6" Grid.Column="0" Grid.ColumnSpan="2" Margin="10" Name="DataGrid_1" ItemsSource="{Binding DataGridData}"></DataGrid>
<Button Grid.Row="6" Grid.Column="2" Margin="10" FontSize="12" Command="{Binding Path=GetDataGridData_Command}">Get Data</Button>

As it is known there are nine boxes and in each box we can put numbers 1-9 without repetition. I am trying to check a given filled Sudoku puzzle whether appropriate numbers are inserted in each of the nine boxes. For the time being I don't consider row repetition and column repetition. I wrote the code using loops and condition
I used 9*9 text-boxes. The names of the textboxes is sequential like for example for the first box
txt11,txt12,txt13
txt14,txt15,txt16
txt17,txt18,txt19
Actually, I used also the controls id to access the text boxes, and each box is checking with the neighboring boxes for equality both in forward -> and backward <-
image
So here is the code
public void BoxCheck() {
int start = 82, end = 74;
int i, b, f;
for (int p = 1; p <= 9; p++, start -= 9, end -= 9) {
richTextBox1.AppendText("Box " + 1);
[Code] ....
This works pretty fine, but is is the right way to do it? it is efficient? Remember for a full checking I have to include row check and column check as well, this is just for checking within each of the 9 boxes in Sudoku.

So I've got a button that has to use 2 textboxes to search for 2 columns in my database.
private void btnFilter_Click(object sender, EventArgs e) {
SQLiteDataAdapter adap = new SQLiteDataAdapter("select * from Test", GetConnection());
DataSet ds = new DataSet();
adap.Fill(ds);
dgvTable.DataSource = ds.Tables[0];
[Code] ....
My Current code for it.
The GetConnection(); and the CloseConnection(); Methods are just making a new connection and closing that connection, if needed I can post that code too later.
But basically, It only "filters" 1 textbox but if I say I want to search the Channel and the Log in which it is in, it doesn't search anything and returns all data in the database.

I have a WPF grid made out of labels with two rows, Apples and Oranges currently without any information. Let's say I want to populate the grid to look like the picture below.
I was wondering what's the best way to populate the labels with a list or array? I was thinking about using a list and passing values into the list
E.g.
List <string> ApplesList = new List<string>();
ApplesList.Add("Red");
ApplesList.Add("Delicious"):
List<string> OrangesList = new List<string>();
OrangesList.Add("Orange");
etc...
But I was wondering it make sense to use a list. Or should I just use an array or 2D array?
Sometimes I wonder when would be best to use a list, array, or 2D array.
